1 Claim.

This invention relates to stabilized suspension of an object againstvibration transmittal therefrom, as the object may receive impacts.

This invention has utility when incorporated in installations adapted toestablish and maintain accuracy of tone for a musical note, especiallyfrom a suspended chime tube in its resonance to impacts.

Referring to the drawing:

Fig. 1 is a front View of a tubular chime assembly embodying theinvention, parts being broken away;

Fig. 2 is a side elevation of portions of the chime assembly of Fig. 1,from the left, the broken away portions being along a sectionapproximately as viewed from the line II-II, Fig. 1;

Fig. 3 is a bottom plan view of the anchor for the suspension hook stemin an insulation disk;

Fig. 4 is a fragmentary narrow-wise View of the hook stem or strap andits connection to a chime tube; and

Fig. 5 is a detail View, in perspective, of the hook, somewhat enlargedover the showing in Fig. 4.

A base or Wall plate I (Figs. 1, 2) has a top outwardly extending angeor bracket portion 2 for supporting a lid or top 3 from which there is ashield 4 as a skirt to an open bottom 5.

In the chamber thus formed there is located on the base I, a plural coilsolenoid housing box 6 (Fig. 1). The showing of the box 6 (Fig. l) isfor the normal or non-energized position of the parts; that is, with nocurrent passing thru the coils in the box 6. At this position, acompression helical spring 'I locates a position of rest for a hammer 8as directed toward but out of contact with a minor diameter resonatortube 9. It is to be noted that this is the recover position for thehammer having non-metallic striker ends with its electromagnet coreportion protruding from the coil with the non-metallic end of the hammer8 clear of abutting contact with the tube 9.

A second helical compression spring Ill is for an additional hammer IIbeing also a solenoid plunger and in parallel with the hammer 8. Thishammer II on its end toward the tube 9 has a soft rubber tip sounddeadener. An offset I2 from a bracket I3 may extend into the path of thehammer I I, thereby limiting the travel of the hammer I I to be short ofstriking the tube 9.

Thru slots I4 in the flange 2 are screws I5 ing leg providing an eye orslot Il. The lower side of the slot I'I has a straight horizontal seat,bearing or rail portion IS. A hook I9 is the upper end of a metal strap20. The hook may be disposed to ride on the seat I8, in providing ahanger joint for the strap 20. A coating 2| of shellac, lacquer orplastic between the throat of the hook and the seat I8 is elTectiVe todampen transmission oi metallic sound and avoids audible disturbance ofchime operation.

Upon energizing a coil in the box 6, the hammer enveloped by such coilis quickly drawn with such speed away from its normal rest position(Fig. l) as to have resonance effecting impact with a tube 22 inparallel with the tube 9 and similarly suspended. This means that as thecoil for the hammer 8 is energized, the hammer 8 strikes rst the tube 22and then the tube 9. In the event the coil for the hammer II isenergized, this hammer II strikes the tube 22, but gives forth no soundfrom the tube 9 on account of the rubber tip at such end, or the holdback stop I2.

A cap 23 has an upwardly iianged central throat opening thru which thestrap extends. This strap end is notched to provide a pair of leafportions 24 which may be thrust thru a central diametrically extendingslot 25 in a fiber insulation disk 26. The portions 24 may then beoppositely offset or iiattened against the underside of the disk 26 inproviding a key assembly and support therefor. A metal disk 21 againstthe underside of the disk 26 locks the offsets 24. This disk assembly isin a skirt or flange 28 integral with the cap 2,3. An end 29 of a majorresonant tube 30 is press tted in the skirt 28 toward the disks 2l, 26,completing the assembly for suspension by the strap 20. The metallicbonding from the tubes 9, 20, may be thru silver solder 32 with thethroat of the cap 23, which is centrally clear .of the strap 20 asedgewise toward the direction of hammer impact on such tubes. The hammerimpacts upon the tube 22 are transmitted therefrom thru the cap 23, itsskirt 28, the chime tube end 29 to the tube 30. The clearance of thestrap 20 from the tube 22 and the throat of the collar or cap 23, hassome yield in a clearance or throat area 33 for the ber disk Z6relatively to the cap 23.

For symmetry of showing, a third or dummy tube 35 may be between thetube 30 and a tube 34 from the tube 9. The tube 35 has therein a woodplug 36 engaged by a strap 20 from a mounting angle brackets I6 eachwith a depend- 55 bracket angle I6.
